Answer:
138 feet
Step-by-step explanation:
plug "3" into the expression by replacing "t" with "3"
-16t^2+83t+33
-16(3)^2+83(3)+33 (remember PEMDAS)
=-16(9)+249+33
=-144+282
=138 (I hope this helps)
Write an equation that can be used to answer the question. Then solve. Round to
the nearest tenth if necessary.
How high is the ramp?
21 ft
19 ft
Oa h + 192 = 212: 8.9 ft
Ob. 21° - 192 = 12:28.3 ft
Och + 192 = 212; 80 ft
Od. h + 19 = 21; 2 ft
what’s the answer

2 supplementary angles are in the ratio 6:3
Find the angles
Answer:
The angels are 60 degrees and 120 degrees
Step-by-step explanation:
The sum of two supplementary angels equal 180 degrees.
So, lets look at the ratio: 6:3
We then add 6 and 3 together which gives us 9.
Then you put it in this equation:
9x = 180
x= 20
- You are adding the two numbers and dividing the sum by 180 because the answer will tell us how much 1 would equal.
- In this case, we multiply 20 by 6 = 120 degrees
- Then we multiply 20 by 3 = 60 degrees.
(We can check our answer by: 120 + 60 = 180 degrees) :)

What is the average rate of change for this function for the interval x=2 to x=4?
Answer:
12
Step-by-step explanation:
The average rate of change in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 2, 4 ]
f(b) = f)4) = 32 ← from table
f(a) = f(2) = 8 ← from table
Then average rate of change is
[tex]\frac{32-8}{4-2}[/tex] = [tex]\frac{24}{2}[/tex] = 12
For the data set 6, 5, 10, 11, 13, the mean, x, is 9. What is the standard deviation?
Answer:
your answer will be 3.4
Step-by-step explanation:
n=number of terms
{6,5,10,11,13}=5
also ∑(x-x)^2=46
[tex]S=\sqrt{\frac{1}{5-1} *46} =[/tex]

Harmony left her dad’s store to go home at twenty to seven in the evening. Forty minutes later, she was home. What time was it when she arrived home?
Answer:
8:00 in the morning .....
Answer:
7:20 pm
Step-by-step explanation:
the phrase "twenty to seven in the evening" implies that is twenty minutes before 7:00 pm, meaning the current time was 6:40 pm.
Adding the 40 minutes it took Harmony to get home, the time would have been 7:20 pm

substitiution method i really need help
Answer:
x = 7
y = 0
Step-by-step explanation:
Equation: 2x - 9y = 14
We are given that x = -6y + 7
So we substitute (-6y + 7) for "x" in the equation 2x - 9y = 14
* substitute *
2 ( -6y + 7 ) - 9y = 14
now we solve for y using basic algebra
step 1 distribute the 2
2 * -6y = -12y
2 * 7 = 14
now we have -12y + 14 - 9y = 14
step 2 combine like terms
-12y - 9y = -21y
now we have -21y + 14 = 14
step 3 subtract 14 from each side
14 - 14 cancels out
14 -14 = 0
now we have -21y = 0
step 4 divide each side by -21
-21y / -21 = y
0 / -21 = 0
we're left with y = 0
now to find x
To find x we substitute 0 for "y" in x = -6y + 7
* substitute *
x = -6 ( 0 ) + 7
-6 * 0 = 0
we're left with x = 7

10. Write an equation in Slope-Intercept Form of the line that is parallel to the graph of
each equation and passes through the given point.
y = 4x + 8
(4,2)
Original slope=
Parallel slope=
Equation=
Answer:
Original slope = 4
Parallel Slope = 4
Equation = y = 4x - 16
Step-by-step explanation:
y = 4x +8
* the slope is the same since it is parallel
2=4(4) + b
2=16 + b
-14=b
y = 4x - 16

A 5ft tall girl is standing 13ft from a 15ft tall lamppost. How long is her shadow?
ill give brainIiest to the right answer
Answer:
[tex]K=6[/tex]
Step-by-step explanation:
In f(x) graph the vertex is at x=4
In g(x) the vertex at x=-2
so, the graph is shifted 6 units left. when the graph is shifted k units left then f(x) becomes f(x+k)
here the graph is 6 units left so.. K= 6

Find the approximate perimeter of the trapezoid? PLSSS HELPPP
Answer:
49
Step-by-step explanation:
side 1 = |18-3|= 15
side 2 = |12-3| = 9
side 3 = |16-4| = 12
side 4: [tex]\sqrt{(18-12)^2 + (4-16)^2} \\ \sqrt{36+144} \\ = \sqrt{180} \\ = 13,4[/tex]
perimeter = 15 + 9 + 12 + 13,4= 49,4 = 49

What is the midpoint of the segment with endpoint(1,9)and(-3,5)
Answer:
(-1 , 7)
Step-by-step explanation:
To find the midpoint, the equation used is:-
[tex]\frac{x1 + x2}{2} , \frac{y1 + y2}{2}[/tex]
Here, the values are:-
x1 = 1
x2 = -3
y1 = 9
y2 = 5
Substituting these in the equation, we get:-
[tex]\frac{-3 + 1}{2} ,\frac{9+5}{2}[/tex]
[tex]\frac{-2}{2} ,\frac{14}{2}[/tex]
(-1, 7)
What is the area of the trapezoid below?
The function f(x) = x2+ 4 is defined over the interval [-2, 2]. If the interval is divided into n equal parts, what is the height of the right endpoint of the k^th rectangle?
Answer:
Following are the responses to the give question:
Step-by-step explanation:
The [tex]f(x) = x^2 + 4[/tex] model is developed in the interval [tex](-2, 2)[/tex] total equal in a between such a range[tex]= 5[/tex].
Its right endpoint of every rectangle is separated onto n equal parts by the height [tex]= \frac{5}{n}.[/tex]
Height of endpoint [tex]= \frac{5}{n}[/tex] of the k rectangles therefore, the height of the kth rectangle = First rectangle height + K rectangle height
[tex]= -2 +k \times \frac{5}{n}\\\\[/tex]
